摘　　要：采用Avio200型电感耦合等离子发射光谱仪,以梨树叶片为试材,对试样的溶解方法、光谱仪的工作参数、精密度、准确度等进行试验研究,确定了适用于梨树叶片中12种矿质元素含量测定的方法。结果表明,元素的检测限为0.0339~3.8003 mg/L,定量限为0.1130~12.668 mg/L,回收率为85.93%~105.45%,相对标准偏差(RSD)为0.99%~4.88%。通过该方法能有效同时测定Ca、P、K等12种矿质元素含量,为梨树叶片营养快速诊断提供方法参考。The Avio200 inductively coupled plasma optical emission spectroscopy(ICP-OES)was used to ascertain the optimal method for detecting 12 kinds of mineral elements in pear leaves,encompassing the dissolution method for samples,along with the working parameters,precision,and accuracy of the spectrometer.The results revealed the detection limits of 0.0339~3.8003 mg/L for the elements,quantitation limits of 0.1130~12.668 mg/L,recovery rates of 85.93%~105.45%,and relative standard deviation(RSD)of 0.99%~4.88%.This method can effectively and simultaneously determine the content of 12 mineral elements,including Ca,P,and K,providing a reference for the rapid nutritional detection of pear leaves.
